SPECIFICATION forming part of Letters Patent N o. 743,843, dated November 10, 1903.

`Application tiled January ZZ, 1903. i Serial No. 140,069. (No model.)

To a/ZZ whom it may concern,.- i

Be it known that I, GET'rIsEiyLELLIoTT, a citizen of the United States, residing `at Chicago, in the county of Cook and State of Illinois, have inventeda certain new and useful Improvement in Wheel-Hubs, of which the vfollowing is a full, clear, and exact descrip- Vforth definitely in the claims.

In the drawings, Figure lis a longitudinal section through the center of the hub, showing all the parts in position. Fig. 2 is a longitudinal section of the barrel, and Fig. 3 is a longitudinal section of one of the flanged sleeves.

Referring to the parts by letters, A represents a wrought-metal barrel, whose end portions a are reduced in diameter by spinning or by some other suitable method.

B B represent sleeves which are fitted onto the reduced end portions of vsaid barrel, abutting the shoulders on the barrel formed by reducing the diameter of the said end portions. These sleeves in the construction shown are held against rotation by means of bosses o forced out from the reduced ends of the barrel into the metal of the sleeves. Each sleeve has on its inner endan integral annular ange b, with which the wheel-spokes are connected. Preferably'these iianges are perforated, as at b, to permit the ends of the spokes to pass through them. Each sleeveis longer than the reduced end of the barrel on which it is secured, and therefore overhangs the same and forms at the ends of the barrels,` but within these overhanging portions of the sleeves, annular recesses in which the ilanges c of the ball-bearing cups C are accommodated. The ball-bearing cups C are forced into the reduced ends of the barrel, and thereby they serve to hold said reduced ends in intimate contact `with the surrounding sleeves. As stated, these ballbearing cups are provided with external annular lian ges c on their outer edges, which lie within the recesses referred to and abut against the eXtreme ends oit' the barrel. A ring E, having a central opening just large enough to accommodate the cones D which are to cop- Aerate with each ball-bearing cup, is inserted into this recess in the overhanging ends of the sleeves and into contact with the outer edges of the ball-bearing cups, and said rings and cups are held in the position shown by the turned-in ends b2 of said sleeves. The cones D and the axle G are of the usual construction. When the spokes are attached to the flanges b on the sleeves B and to the wheelrim and are tightened up, they also serve to hold the flanged sleeves on the barrel and against the shoulder thereon, and thereby help to hold all `the parts in the described positions.

Having described my invention, I claiml. In a wheel-hub, the combination with a wroughtmetal barrel having reduced end portions, iianged sleeves secured upon said reduced end portions andoverhanging the same, ball-bearing cups iitted into the reduced end portions of said barrels and having external anges which abut the ends of said barrels and lie within the overhanging parts of said sleeves, the outer ends of said sleeves being turned inward to hold said cups in, substantially as specified.
